Offset for 8.5J is +21. P.C.D = 114.3. Hole = 5H. Color = RMC. Offset for 9.5J is +23. P.C.D. = 114.3. Hole = 5H. Color = RMC. will these wheels fit the rx8? what size tire should I do if they do fit? do i need wheel spacer fot it?

 

yes and yes..
go to the tire rack they have a chart on there site .. it will help
ohh and i have some sweet rims for sale,,

 

but how come I go to some other website, they all use offset +40 or up??? does it make any difference? what is the difference???

 

Whoa those offsets are WAY too low..won't work on the 8

 

really? thanks!

 

it just depends on your taste , the size of the tire and the size of the wheel.

Some people are willing to have a bit of rub. others no way. ...


Fo instance Look at the wheels i have for sale in my forum. HE has those set up for just about max. He has no rubbbing and Looks great. But for some that a bit to much..

These are 4 Racing Hart J-8 2pc forged 19x10 +44 offset rear
and 19x8.5 +38 offset front with Nitto tires 555 275/30/19 rear and 245/35/19 front.

there is a big difference between the size he asked about and the ones you refer to here. For the wheels he asked about the front would stick out 17mm further out than the wheels you list and the rear would be 14mm further out.
now if those wheels you list are the maximum then how can he fit 1/2" more under the guards?
